Mems oscillator corners quartz oscillator in multiple performance parameters

The mems-based oscillator device from SiTime outperforms crystal oscillator in the areas of power, size and weight. SiTime claims its SiT8021 consumes 90% lower power, is 40% smaller, and 70% lighter than quartz devices. If you're looking for some good saving in power consumption and physical size in mobile devices such as smart watches, fitness bands, tablets, smart phones, portable audio and accessories, it is a good idea to explore SiTime's this new oscillator SiT8021.

“In 2013 and 2014, SiTime introduced the smallest, lowest power 32 kHz oscillator and TCXO for the wearables, IoT and mobile markets. These products were based on SiTime’s game-changing TempFlat MEMS and low-power programmable analog technology. Customers adopted these 32 kHz XOs and TCXOs rapidly – we expect to ship several tens of millions of units in 2015,” said Piyush Sevalia, executive vice president of marketing at SiTime. “Innovating rapidly, SiTime used our revolutionary technologies to deliver the μPower family of MHz MEMS oscillators. This new family of oscillators breaks through the limitation of quartz technology and enables smaller electronic devices with dramatically longer battery life.”

“Wearables and IoT are generating a lot of excitement as they are expected to drive the future growth of the semiconductor industry,” said Tony Massimini, Chief of Technology at Semico Research. “SiTime, with its leadership in Silicon MEMS timing solutions, is in a unique position to capitalize on the rapid growth of wearables and IoT.”
